On August 30, BTOBs Yook Sungjae held a V Live broadcast to talk about the release of his solo single album for BTOBs ongoing solo single project Piece of BTOB.
He shared, Paradise [one of the songs on the album] is self-produced. I felt shy about putting out songs that was just my voice and also self-produced. I still have a long way to go in making my own songs so I didnt even let the BTOB members listen to it. I told them to listen to it when it came out.
